clk: qcom: camcc-sc7280: Add parent dependency to all camera GDSCs

[ Upstream commit 63aec3e4d987fd43237f557460345bca3b51e530 ]

Camera titan top GDSC is a parent supply to all other camera GDSCs. Titan
top GDSC is required to be enabled before enabling any other camera GDSCs
and it should be disabled only after all other camera GDSCs are disabled.
Ensure this behavior by marking titan top GDSC as parent of all other
camera GDSCs.
